Description
Technical field
This utility model relates to the annealing of gear shaft screw thread, particularly gear shaft screw thread annealing device.
Background technology
Annealing refers to be heated slowly to metal uniform temperature, keeps enough time, then cools down with Reasonable Speed.Purpose is to reduce hardness, improves machinability；Eliminate residual stress, stable dimensions, reduce deformation and be inclined to crackle；Crystal grain thinning, adjusts tissue, eliminates tissue defects.The annealing of gas cylinder, is to eliminate internal stress, reaches good plasticity.Annealing furnace, is to implement the machine that annealing process is used.
Existing gear shaft makes annealing treatment at annealing furnace, it is impossible to make gear shaft surface thermally equivalent, causes its annealing effect bad, and at annealing in-furnace temperature, it is impossible to control, be therefore difficulty with thermostatic control, also cause its annealing effect bad.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of simple in construction, be heated evenly the gear shaft screw thread annealing device good with annealing quality.
The purpose of this utility model is achieved through the following technical solutions: gear shaft screw thread annealing device, it includes main shaft, taper-shank arbor, radiator, upper top, under top, heating inductor and workpiece, one end of described taper-shank arbor is sleeved in main shaft, and fastened by trip bolt A, the other end of described taper-shank arbor is sleeved on top interior, and fastened by trip bolt B, described radiator muff-joint is contained on taper-shank arbor, and the upper end of radiator is by the upper top step withstanding on taper-shank arbor, on the described upper top upper end center hole withstanding on workpiece, under on the top lower center hole withstanding on workpiece, the end of thread of described workpiece is positioned at heating inductor.
Described upper top employing non-magnet_conductible material is made.
This utility model has the advantage that annealing device of the present utility model, use magnetic field heating, by the uniform rotation of workpiece, thus realize thermostatic control, and be provided with radiator, can timely by upper top on heat scatter and disappear, thus avoid top thermoplastic deformation, ensure that workpiece axiality in rotation process, so that workpiece is heated evenly, improve the annealing quality of workpiece.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In figure, 1-main shaft, 2-trip bolt A, 3-taper-shank arbor, 4-radiator, top under 5-, 6-trip bolt B, 7-are upper top, 8-heating inductor, 9-workpiece.
Detailed description of the invention
Being further described this utility model below in conjunction with the accompanying drawings, protection domain of the present utility model is not limited to the following stated:
nullAs shown in Figure 1，Gear shaft screw thread annealing device，It includes main shaft 1、Taper-shank arbor 3、Radiator 4、Upper top 7，Under top 5、Heating inductor 8 and workpiece 9，One end of described taper-shank arbor 3 is sleeved in main shaft 1，And fastened by trip bolt A2，In the other end of described taper-shank arbor 3 is sleeved on top 7，And fastened by trip bolt B6，Described radiator 4 is sleeved on taper-shank arbor 3，And the upper end of radiator 4 withstands on the step of taper-shank arbor 3 by upper top 7，Heat on upper top 5 can be dissipated by radiator 4 in time，Prevent top 5 thermoplastic deformation，Thus ensure that the axiality that workpiece 9 rotates，Avoid workpiece 9 deflection，Thus ensure that the degree of being heated evenly of workpiece 9，Improve the annealing quality of gear shaft，Described upper top 7 withstand on the upper end center hole of workpiece 9，Under top 5 withstand on the lower center hole of workpiece 9，The end of thread of described workpiece 9 is positioned at heating inductor 8，Heating inductor 8 uses magnetic induction to heat，I.e. heating inductor 8 produces magnetic field，Workpiece 9 is in rotation process，Will cutting magnetic field，Thus produce heat energy，Complete the annealing of gear shaft screw thread.
In the present embodiment, described upper top 7 use non-magnet_conductible material to make, thus improve the utilization rate in magnetic field, improve the efficiency of heating surface of workpiece 9.
Work process of the present utility model is as follows: main shaft 1 rotates under use in doing of driving motor, thus drive taper-shank arbor 3 to rotate, taper-shank arbor 3 drives workpiece 9 to rotate, after workpiece 9 rotates, workpiece 9 will cutting magnetic induction line, so that workpiece 9 is heated, complete the annealing to workpiece 9 end of thread, in whole annealing process, because being provided with radiator, make top 7 and taper-shank arbor 3 on heat can quickly scatter and disappear, thus avoid top 7 and the thermoplastic deformation of taper-shank arbor 3, ensure that rotating coaxially of workpiece 9, thus ensure that workpiece 9 is heated evenly, improve the annealing quality of workpiece 9.
